I'm afraid of the unknown.  What terrifies me is not what is really out there but what could be out there.  I have a strong mind and I can imagine a million horrors that can be visited upon me and my friends.  However, is it true?  Most of what is out there isn't really there to hurt me.  It is just there.  But, in the reality that I was brought up in, everything that I don't know will hurt me.  It's conditioning that is hard to let go.  I'm sure that that conditioning has prevented me from taking chances that could have helped me.  I'm still afraid.
